Evolution is not that simple. There is no selective pressure for a feature if it does not ultimately in some way benefit reproduction or the offspring. Vegetables are healthy for us now because we live much longer than we used to in an environment not dominated by us, and they contain many nutrients which help to sustain a healthy body beyond, say, 50. ...

I'm guessing that what they mean by 'maximize nutrition' for digestion is that they are assuming that the cells are broken open. This would make the co-factors we call vitamins, protein and sugars freely available to the digestive system and more easily absorbed. I think it is a marketing literature claim, though the blender may have some valid ...

You're missing that potatoes also reproduce sexually. They're flowering plants, and they produce seeds that are not genetically identical to their parent plants.

A true fruit is a ripened ovary that usually starts ripening when it is fertilized. And vegetable is any vegetative part of the plant which is edible and contains stored food probably in the form of starch. These definitions are not exact as there are a lot of fruits which are fruits but do not strictly follow the given definition. See Syconus, Composite ...

Depends on the container. The bottom of the ocean has three main properties that would affect the rice: Water Salt and floating materials Pressure - at the bottom of the Mariana Trench, the pressure is 1000x that standard atmospheric pressure at sea level. Rice is absorbent. Depending on the container, if it is permeable to water, then both seawater ...

Vegetables provide calories and don't kill you. For a hunter-gatherer, that's reason enough to eat them even if you don't like the flavor a lot. Finding nourishing foods "repellent" is a modern luxury. Additionally, the bitter flavors in vegetables may be less noticeable to people who were not raised from infancy with hyperpalatable, sugar-sweetened food.

Well, uvesten is correct in saying that potatoes are flowering plants and as such they can reproduce sexually. However, as everyone mentions potatoes can, like many plants, reproduce asexually by putting out clones. Since clones are (by definition) genetically identical to the parent plant, this would seem to rule out the possibility of producing different ...

First we will take a look at the lines of resistance of a carrot. There are three The skin - The first line of resistance is the outer membrane or skin of the carrot and chemical compounds that are normally present there. Two antifungal polyacetylenes, falcarinol and falcarindiol, and an isocoumarin, 6-methoxymellein, are present in small amounts in ...

Vitamin C and the B complex vitamins are water soluble. Thiamine and folate are also heat labile. Overall there are hundreds or often thousands of kinds of small molecules (not protein or DNA) in the cell and many of them are water soluble or heat labile. Plants especially have many unusual small molecules. Its not known how many of them affect human ...
